Firstly, each codon is formed by three nucleotides, that codify for an amino acid.
In the chart of the left, the first nucleotide is represented on the left column, the second is represented by the row on the top, and the third nucleotide is represented by the column on the right. In the intersection of these three, is the amino acid corresponding to the nucleotide triplet.
The right chart, has to be followed from the center to the external part, so the first circle, that is divided in four, represents the first nucleotide, while the amino acid is located in the most external part of the chart.
what is the purpose of DNA replication and why is it important that dna replito. it's before mitosis
Answer:
Mitosis is where the cell divides itself into two identical parts.
In order for the two cells to be identical, they need to have the same parts, which is where replication is important
If the cell didn't replicate its organelles, it would not be able to split itself since nothing would go into one of the halves
Replication is the duplication of those organelles so that the sister cells are the same, so making a copy of the nucleus and other organelles allows one of those parts to stay and one part to go into the new cell

What causes the formation of acetone, which eventually leaves the body through the lungs, causing breath with a fruity smell?.
The formation of acetone which eventually leaves the body through the lungs causes breath with a fruity smell is ketosis.
Ketone bodies are formed in liver cells through the breakdown of fatty acids. They are released into the blood after the glycogen stores in the liver are depleted. Oxygen and glucose are used by cells to produce the energy-rich ATP molecules needed to maintain cellular metabolism. This process is called cellular respiration. The lack of mitochondria means the cells don't use the oxygen they carry.
It produces the energy carrier ATP through fermentation glycolysis of glucose and lactate production. When glycolysis is blocked red blood cells lose their membrane potential and eventually die. Mature mammalian red blood cells are incapable of aerobic respiration, the process by which organisms convert energy in the presence of oxygen, and glycolysis is the sole source of ATP.

What happens when metabolism is high?You will consume more calories both at rest and when you are active if your metabolism is "strong" (or fast). You'll need to consume more calories to sustain your weight if you have a high metabolism. One theory for why some persons can eat more food than others without weight gain is because of this.
How does metabolism operate?The process through which the body converts food and liquids into energy is called metabolism. To create that energy your body requires, calories from food and beverages combine with oxygen throughout this process. A body requires energy for all its functions, even when at rest.

Monozygotic twins occur when a fertilized egg undergoes mitosis, and the two cells that result become separated and develop independently. What is the genetic relationship between the two offspring?.
Genetically speaking, the two offspring are identical. They thrive from a single fertilized egg that divides in two.
What does the term "monozygotic twins" mean?
Monozygotic twins are produced when a single egg is fertilized by a single sperm in the fallopian tube, resulting in the fertilized egg dividing into two. These twins have the same sex chromosome and the same genome.
A fertilized egg may split within a few days of conception, producing genetically identical twins. These twins are known as monozygotic because they are descended from a single zygote. Identical twins are of the same gender.

Involuntary muscles are those whose function cannot be controlled. They are muscles with a spindle shape. These have no nucleus. The autonomic nervous system (ANS) is primarily responsible for its control.
Hormones, ANS neural stimulation, and local factors can all trigger smooth muscle involuntary control. The muscle can contract when stretched in certain places, like the walls of visceral organs.

Dimerization is the first step following platelet-derived growth factor (pdgf) binding of the receptor.
A dimer is created when two molecules with similar chemical compositions come together during this process. When carbonylic acids are anhydrous, the acidic hydrogen and carbonyl oxygen form dimers. For instance, acetic acid forms a dimer in the gas phase, where hydrogen bonds hold the monomer units together. Most OH-containing molecules can form dimers, such as the water dimer, under specific circumstances. Cross-dimerization, the process by which isobutene and 2-butene react, creates a mixture of octene isomers that go by the name cross-dimer. Both cDIM and DIB are regarded as beneficial products.

If a man with classic hemophilia (x-linked recessive) has children with a woman who is a carrier for the disorder, the expected risk pattern is 50% .
Recessive inheritance is evident in the majority of X-chromosome diseases. Males are more likely than females to get these disorders because they only have one copy of the X chromosome. Each boy born to a female who has an X-linked recessive trait has a 50% chance of inheriting the trait, but no daughters of this mother would be anticipated to be afflicted (each daughter has a 50% chance of being a carrier). Having received their father's Y chromosome, the sons would not be affected (there is therefore no male-to-male transmission), whereas an affected father passes the mutation to all of his carriers daughters.

Under resting cellular conditions, the concentration of potassium is greater inside the, and the plasma membrane is most permeable to potassium.
The resting membrane potential, or simply the resting potential, is the voltage across the membrane of a resting (non-signaling) neuron. Ion concentration gradients across the membrane and the permeability of the membrane to each type of ion determine the resting potential. Na+ and K+ both have concentration gradients across the membrane of a resting neuron. Through channels, ions descend their gradients, resulting in a charge separation that generates the resting potential.

What is enzyme substrate complex?The first step in the process of enzyme catalysis is the enzyme's binding to its substrate, which results in the formation of an enzyme-substrate complex. The active site is a particular area of the enzyme that the substrate binds to in order to make it active. The substrate is changed into the product of the reaction while it is still connected to the active site of the enzyme. After this transformation, the product is subsequently released from the enzyme.
